The "Sasha" Thread

Tango, I want him to sign the scooter, not the paperwork. I really don't care if he signs it or not but it would be cool. I could buy the picture in the link below and sell it with the scooter as a package deal I suppose.

It won't be the first scooter he's signed:




On a side note, I went outside and the scooter started for a couple seconds, died and won't restart. It has spark so I'm thinking the damn carb filled up with oil again.

Okay...I gotcha.

Yep, it was a drop kick then :lol2:

Okay, so I finally got time to start back to work on "Sasha" today. I go out this morning to find a puddle of oil under the air filter. Maybe 1/4 cup or so. I proceeded to disassemble everything and clean it all. I poured gas in the pipe and sloshed it around in there twice. I cleaned the air filter and removed the fan shroud and cleaned all the muck out of every crevice of the engine and frame and put it all back together. She fired up and runs perfect! Some initial smoke and some oily gas shot out but it wasn't for long and she started smoking a lot less. Starts up at the first touch of the button when warm. I'm gonna let her sit all night before I put all the body on to see if the oil is still gonna fill up the carb and intake again. My zip used to leak a little oily gas from the air filter when I first got it but it stopped after a week or two.

Has anyone else had this issue of oil leeching past the pump like that?

If you are getting a puddle you only have 1 of 2 solutions to choose from.

1) Replace the oil pump. If you wanna keep as stock as possible do this.

2) Ditch the injector system totally and pre-mix your gas. This is what I do on all my 2t's

See when the pump dies they can let oil flow on through as what is happening to you. They can also just stop flowing completely at which point you toast your engine if you don't catch the problem. I often see them set to high via cable tension fowling plugs and leaving a ton of carbon in the engines and oil in the exhaust. I have also seen the plastic gear that runs the pumps get chewed up and let the engine go oil-less.

I just received information that leads me to believe that the check valve on the carb where the oil tube connects is possibly bad however, I just went out and looked at the oil tank cap and it was screwed on crooked. I righted it and tightened it up tight so we'll see what happens in the morn'.

The cable has 1/8th to 3/16 of play in it.

I've had the oil pump leaking issue. I decided to remove it a few weeks back (still working on it) and I split the crankcase. As soon as it started to come apart, oil started dribbling out. I shined a flashlight in through the intake, and the entire crankcase had been full of oil. It was only sitting for about 2 months, too. Had to have been leaking at the pump and working it's way up to the carb, down through the reeds, and pooling in the crankcase.

I think I'm having the very same problem with mine. I'm in the process of replacing the carb to see if that cures the problem. I need to get rid of that carb anyway...with that and the bad auto enricher...too much going wrong with it now.

[jmkjr72]

yeah i have had to take the check valve apart on some older hondas and clean it up
as the old oil would cause the ball to get stuck
only one time have i actualy seen a weak spring in one

[tango]

Hang on a sec JM...where's the check valve you're talking about? Isn't that the little nipple on the side of the carb where the oil inlet goes into it? Or is there something else I should be looking at?

[jmkjr72]

it should be on the inside of that nipple9well on the carb side of that nipple) where the oil goes into the carb its just a spring and ball
the spring forces the ball to seat on the inside of the needle
when the engine is turning and oil is pumping it pushes the ball back into the spring and lets oil flow

[Reign]

Well then theres definitely something wrong with all of the carbs I've ever owned. They're all just open ports for the oil intake. No ball or spring inside.

[mr808]

There could be a check valve problem if one is present. Regardless of that the pump is definitely letting oil flow past so yes it could be two problems the valve is stuck open or not present and the pump is letting oil flow on through.

Reign not all carbs I have worked on have them but most do. To see you have to take that brass nipple out. I have also seen some that have the ball and spring removed. It's best to have one and have it functioning properly if you are running oil injection.

[Fox]

Well, I went out this morning and found no oil puddle. Pressed the button and she fired up instantly. I think maybe the little check valve decided to work but I'm going to let it sit a couple more days before I button her all up because if there is a problem I don't want to have to strip the plastics off her again. it's not exactly a quick job to get the plastic off.

[jmkjr72]

some times you can glean it by just squirting starting fluid in

yeah not all of them have check valves and unless you pull the nipple you wont see the ball and spring

i have also seen them with the check valve actualy in the oil pump too
